Best pistons for street 340?

I run the KB-243 pistons. Good quality piston for the price. Been in my engine for 20 years no problems. Just make sure to follow instructions for ring gap.

The KB 243 'Hypereutectic' is an excellent choice, as they have been
'tried and true' tested and are proved to be reliable.
